I agree with deepti.. you can carry rice and dal.. lightly dry roast rice and dal (separately or together) and blend them... you can carry them with you and cook and feed... also if you want to carry nestum or cerelac please ensure your baby is able to digest them a few days before your journey.. don't start anything directly when away..

Nestum rice is better than cerelac, it doesn't have milk and added sugar while celerac does, you can carry home made rice daal porridge and cook wherever you are that will be more healthy option for your kid.
